 What is a Lithium-ion Backup Battery?

A lithium-ion backup battery is becoming a popular choice for charging both indoor and outdoor appliances. These batteries can store energy or power that can be used later, especially during power outages or outdoor trips. When paired with solar panels, it becomes an ultimate solar generator to charge all electrical devices.

Jackery Explorer Portable Power Stations feature NMC lithium-ion or LiFePO4 batteries that can last long and require little maintenance. For example, the compact Jackery Explorer 300 Plus Portable Power Station has a LiFePO4 battery of 288Wh capacity and is ideal for outdoor excursions. On the other hand, the large Jackery Explorer 3000 Pro Portable Power Station acts as a whole-home charging solution for all home devices.

Why Do You Need a Lithium-ion Backup Battery?

Lithium-ion batteries are popular power sources for home and outdoor needs. They have a high energy density and can store more power in a small space. It can last longer compared to lead acid batteries and can even handle more discharge/charge cycles. Here are some reasons to choose a lithium-ion backup battery:

  • Generally speaking, lithium-ion batteries have a higher power density to offer more power in small spaces. For this reason, you can choose a small lithium-ion battery and carry it while camping, off-road trips, etc.
  • They can even work in extremely low temperatures, so you can power appliances in freezing climates.
  • These Li batteries are light in weight and offer interrupted supply to most outdoor appliances.
  • There are whole-home lithium-ion battery backups that can be integrated with home circuits to start charging essential appliances in a few seconds.

How Does Lithium-ion Backup Battery Work?

The lithium-ion battery backups work when positive lithium ions move from the positive to negative electrode and negative electrodes from negative to positive end. The Jackery Explorer Portable Power Station featuring LiFePO4 or NMC lithium-ion batteries works by supplying continuous electricity to the appliances.

When the direct sun's rays fall on the monocrystalline silicon solar cells of the Jackery SolarSaga Solar Panels, the free solar energy is converted into DC current. The Jackery Explorer Portable Power Stations have a pure sine wave inverter that works by converting DC to AC electricity, which is then transferred to charge devices.how does lithium-ion battery backup works

How to Choose the Best Lithium-ion Backup Battery?

Lithium-ion batteries are often one of the most expensive components in the solar power system. For this reason, it is essential to carefully consider a few factors to choose the best lithium-ion battery backup.


The capacity of a battery is the amount of electricity it can store and is typically measured in watt-hours or kilowatt-hours. You'll need to understand the wattage requirement to calculate the correct battery capacity. Start by adding the appliance wattage you want to charge and then choose a lithium-ion battery backup that can supply sufficient electricity.

Safe and Clean

The battery backup of your choice should provide clean energy to all the appliances. It should not emit any toxic fumes or noise, ensuring the appliances get clean energy. Jackery Explorer Portable Power Stations are built with advanced BMS (Battery Management System) to provide over-voltage and short-circuit protection. These solar batteries use free and clean solar energy to produce electricity.

Cell Type

Lithium Nickel Manganese Cobalt Oxide (NMC) and LiFePO4 are popular cell types for power stations and battery backups. Lithium-ion battery backups have a longer lifespan and higher energy density than lead-acid variants.

Input/Output Ports

Battery backups with more output ports can help you charge multiple appliances simultaneously. Jackery Explorer Portable Power Stations feature many AC, USB-A, and USB-C ports to charge small and large home appliances for long hours.


The battery lifespan is another critical factor you must remember while choosing the best battery-powered backup. For example, the LiFePO4 and lithium-ion batteries can last up to 10 years if maintained well.

Lithium-ion Backup Battery FAQs

How long does a lithium-ion battery backup last?

Lithium-ion battery backups can typically last up to 5 years or 2000-3000 charging cycles, depending on the quality of the cell type used. Jackery Explorer Portable Power Stations feature a lithium-ion or LiFePO4 battery that has a lifespan of over 10 years.

How long do lithium-ion UPS batteries work?

The lithium-ion UPS battery backup can last 6-10 years, often as long as the UPS itself.

Can I replace the UPS battery with lithium-ion?

Yes. You can replace the UPS battery with lithium-ion in an uninterruptible power system. However, these lithium-ion batteries can destroy charging circuits in low-quality UPSs.

Are backup batteries lithium-ion?

Yes. Many battery backups use lithium-ion battery cells as they perform pretty well and have advanced safety features. Jackery Solar Generators have NMC lithium-ion and LiFePO4 batteries to charge all the appliances safely for long hours.


Unlike lead-acid batteries, a lithium-ion backup battery has high energy density. That means even tiny and compact batteries can provide a lot of energy to the appliances being charged. Many lithium-ion battery backups are available out there, but not all are the same. Some are made with LiFePO4 battery cells that typically have a long lifespan and supply steady electric charge to devices.

Jackery manufactures different sizes and capacities of Jackery Explorer Portable Power Stations with NMC or LiFePO4 cells. If you want an outdoor solution to power outdoor devices like smartphones, then the lightweight and travel-friendly Jackery Explorer 100 Plus Portable Power Station is the ideal choice.
